Ok, so you use 4 blackberries with your account. Since it works fine for you, does it mean it will work in my situation?

I have my own blackberry now. It runs off my work's enterprise server. My work wants everyone to use a corporate blackberry (one that they would buy for us and that they own). I would continue to use my own bb as my phone, but I don't want to carry two blackberries around.

Can I let IT sync the work bb, then I sync my own bb on my own, and ditch the corporate bb and continue to use my own without them knowing?
